[0001] The invention relates to the technical field of steel bar bending detection, and in particular to a curvature-adjustable steel bar bending detection device. Background Art

[0002] The steel bar bending test is a test of the steel bar to evaluate its bending performance and strength. This test is an important part of steel bar quality control and is crucial to ensure the safety and reliability of steel bar use. The steps are generally to select suitable test steel bar samples, pre-treat the steel bar samples, including cleaning, degreasing and derusting, install the steel bar samples on the testing machine, apply bending load, record the stress-strain data during the test, and analyze and evaluate the test results.

[0003] When in use, the existing steel bar bending detection equipment often completes the bending of the steel bars by squeezing the rollers. However, due to the wide variety of sizes of steel bars, when detecting the bending performance of steel bars of different national standard sizes, it is necessary to constantly disassemble and replace rollers of different models, which results in a slow efficiency in the detection of the bending of steel bars of various sizes. The existing steel bar bending detection equipment has poor detection applicability and is more cumbersome to operate, so there is a need to improve the detection equipment. Summary of the invention

[0034] Reference Figure 1 - Figure 6 , curvature adjustable steel bar bending detection equipment, including: The bottom frame 1 has a bracket 11 fixedly connected to the top thereof to support the bracket 11, and a servo motor for controlling the rotation of the ball screw 23 is installed on the bracket 11; The pushing mechanism 2 is arranged at the top of the base frame 1 and is used to push the steel bars for bending. The pushing mechanism 2 includes a slider 22, which is slidably connected to the base frame 1. A through groove is provided on the slider 22, and the through groove is convenient for accommodating the moving plate 33 of the support and adjustment mechanism 3 to slide, so that the support and adjustment mechanism 3 and the slider 22 move synchronously; The support adjustment mechanism 3 is arranged on the slider 22. The support adjustment mechanism 3 includes a motor 31, a bidirectional threaded screw 32, a movable plate 33, an extension plate 34 and a steel column 35. The motor 31 is fixedly connected to the slider 22, and its output shaft is coaxially fixedly connected to the bidirectional threaded screw 32. The bidirectional threaded screw 32 is arranged in a through groove and is rotatably connected to the inner wall of the slider 22. The movable plate 33 is provided with two and respectively connected with two sections of threads of the bidirectional threaded screw 32, so that the two movable plates 33 are conveniently close to or away from each other. The extension plate 34 is fixedly connected to the movable plate 33 according to the size of the steel bar, and the steel column 35 is rotatably connected to the movable plate 33. The length of the extension plate 34 exceeds the side of the steel column 35 away from the bracket 11, so as to provide support space and bending space when the steel bar is bent; The transmission box 4 is fixedly connected to the base frame 1 and is arranged on a side away from the bracket 11. The transmission box 4 is provided with a power mechanism. The power mechanism is externally transmission-connected with a rotating rod 43 to control the rotation of the rotating rod 43, thereby switching the curvature block 46 to improve the convenience of equipment operation. A rotating disk 45 is coaxially fixedly connected to the outer side of the rotating rod 43. A plurality of curvature blocks 46 of different sizes are arranged in a circular array on the outer side of the rotating disk 45. Support plates 47 fixedly connected to the base frame 1 are symmetrically arranged on both sides of the rotating disk 45. The rotating rod 43 penetrates the support plate 47 and is rotationally connected to the support plate 47. The protection box 5 is arranged between the support adjustment mechanism 3 and the turntable 45. The interior of the protection box 5 is in a cavity shape, and the side close to the support adjustment mechanism 3 is an open structure. The side of the protection box 5 close to the turntable 45 is provided with an arc-shaped through groove to protect the bending area of ​​the steel bar to prevent the steel bar from flying after breaking and causing unnecessary accidental injuries; The safety locking mechanism 6 is arranged at the inner side of the protection box 5 and is in contact with the extension plate 34 for transmission.

[0035] Specifically, when in use, first, according to the actual size of the steel bar, the rotation of the bidirectional threaded screw 32 is controlled by the motor 31, so as to control the moving plates 33 to move closer to or away from each other, and the steel bar is placed on the extension plate 34. The power mechanism drives the rotating rod 43 to rotate, and the rotating rod 43 drives the turntable 45 to rotate. After selecting a suitable curvature block 46, the power mechanism is stopped, and the pushing mechanism 2 pushes the steel bar and the curvature block 46 for extrusion until the steel bar breaks. The stress and strain data during the test are recorded to analyze and evaluate the test results. During the detection process, the extension plate 34 moves and contacts the safety locking mechanism 6 through the push rod 341 to limit the turntable 45 to ensure that the turntable 45 remains stable when the curvature block 46 and the steel bar are squeezed, and the protection box 5 limits the broken steel bar to prevent the steel bar from popping out, thereby improving the safety of the detection equipment during operation.

[0036] Reference Figure 1 - Figure 4 Specifically, in the embodiment of the present invention, the pushing mechanism 2 also includes a limit rod 21, a ball screw 23 and an end fixing block 24. The limit rod 21 is arranged parallel to the ball screw 23, and the two ends of the limit rod 21 are respectively fixedly connected to the end fixing block 24 and the bracket 11, and the two ends of the ball screw 23 are respectively rotatably connected to the end fixing block 24 and the bracket 11. The limit rod 21 and the ball screw 23 both pass through the slider 22, and the slider 22 is slidably connected to the ball screw 23.

[0037] In the embodiment of the present invention, when controlling the bending of the steel bar, the servo motor first controls the ball screw 23 to rotate, so that the slider 22 slides horizontally along the limit rod 21, and finally sends the steel bar into the protection box 5 for bending until the steel bar breaks.

[0038] Reference Figure 3Specifically, in the embodiment of the present invention, a side of the slider 22 close to the bracket 11 is fixedly connected with an anti-collision block 221 , and the length of the anti-collision block 221 is greater than half of the maximum width of the bracket 11 .

[0039] In the embodiment of the present invention, during the recovery of the slider 22 , the anti-collision block 221 contacts the bracket 11 before the motor 31 , so that the motor 31 does not collide with the bracket 11 , thereby protecting the motor 31 and extending the service life of the motor 31 .

[0040] Reference Figure 2 and Figure 4 Specifically, in the embodiment of the present invention, a push rod 341 is fixedly connected to the bottom end of the extension plate 34 , and the bottom end of the push rod 341 is lower than the bottom surface of the clamping rod 63 .

[0041] In the embodiment of the present invention, during the process of pushing the steel bars, when the push rod 341 contacts the clamping rod 63, the clamping rod 63 is clamped between the two curvature blocks 46. In order to further enhance the stability of the clamping rod 63 when it is clamped, a clamping groove that is compatible with the clamping rod 63 can be opened on the turntable 45. Grooving is a prior art and will not be described in detail and is not shown in the figure.

[0042] Reference Figure 2 - Figure 4 Specifically, in the embodiment of the present invention, an arc-shaped slide groove is provided on the surface of the extension plate 34, and an arc-shaped baffle plate 36 is slidably connected in the arc-shaped slide groove.

[0043] In the embodiment of the present invention, when the steel bars are transported for bending, the arc-shaped baffle plate 36 prevents the steel bars from rolling off the front end of the extension plate 34. When the steel bars are bent and contact the arc-shaped baffle plate 36, the arc-shaped baffle plate 36 slides along the arc-shaped slide groove, thereby not hindering the bending of the steel bars.

[0044] Reference Figure 1 Specifically, in the embodiment of the present invention, the power mechanism includes a motor 41, a worm 42 and a worm wheel 44. The motor 41 is fixedly connected to the transmission box 4, and its output shaft is coaxially fixedly connected to the worm 42. The worm wheel 44 is coaxially fixedly connected to the rotating rod 43, and the worm wheel 44 is transmission-connected to the worm 42.

[0045] In the embodiment of the present invention, when switching the curvature block 46, the motor 41 is started to drive the worm 42 to rotate, the worm 42 drives the worm wheel 44 to rotate, and the worm wheel 44 drives the rotating rod 43 to rotate, and finally the rotation of the turntable 45 is completed, and the curvature block 46 is switched. It should be noted that each curvature block 46 corresponds to a national standard of steel bars, so it is suitable for rapid bending detection of different steel bars.

[0046] Reference Figure 2 , Figure 5 and Figure 6Specifically, in the embodiment of the present invention, the safety locking mechanism 6 includes a limit box 61 and a reset spring 64. The limit box 61 is provided with two and symmetrically distributed on both sides of the turntable 45. The limit box 61 is fixedly connected to the top surface of the base frame 1. A slide groove 62 is provided in the limit box 61. A clamping rod 63 is slidably connected in the slide groove 62. Both ends of the clamping rod 63 are slidably connected to the inner wall of the protection box 5. A reset spring 64 is fixedly connected between the clamping rod 63 and the inner wall of the slide groove 62. The thickness of the clamping rod 63 is less than the distance between two adjacent curvature blocks 46, ensuring that it can be clamped between the two curvature blocks 46 to limit and reinforce the turntable 45 to prevent it from rotating at will.

[0047] In the embodiment of the present invention, during auxiliary locking, the locking rod 63 is locked between the two curvature blocks 46 under the action of the push rod 341. At this time, the reset spring 64 is in a compressed state, releasing the contact between the push rod 341 and the locking rod 63. Under the action of the reset spring 64, the locking rod 63 is pushed to reset, so that the locking rod 63 will not affect the rotation of the turntable 45, ensuring the rapid switching of the curvature block 46.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
